• Abstract:

  The study Atmospheric pressure plasma technology has become a prominent area of research due to its diverse applications in health. Areas such as pollution control, materials processing, electrochemistry and engineering as a whole have this technology as very relevant. The moment in which the chemical species in the plasma reach the treated surfaces still requires studies, so the current search aims to obtain deeper knowledge for applications in dentistry. Special attention is paid to the biological and surface effects of plasma-generated reactive species. It is the research aims to use the Optical Emission Spectroscopy (EEO) technique, a tool for plasma diagnosis, detection of reactive species and their identification, as well as the analysis of how they behave according to the parameters adopted in the process. to obtain plasma by Dielectric Barrier Discharge (DBD). To carry out this analysis, it was necessary to follow the steps search of articles to carry out the literature review, laboratory experiments to obtain data and analysis of reactive species. The results include graphs of the plasma spectrum, with its respective parameters, as well as the identification of its chemical species, with thermal images of some samples under incidence of the plasma plume, considered critical for dentistry. It is concluded that the study of reactive species is very important for several areas, especially dentistry, as the chemicals species in addition to carrying out superficial modifications, increasing the applied energy, inactive unwanted microorganisms, with sterilizing effect.
